Take-Two sent a cease-and-desist letter to the developers behind the OpenIV modding tool. Rockstar Games issued the following statement to IGN:

"Take-Two’s actions were not specifically targeting single player mods. Unfortunately, OpenIV enables recent malicious mods that allow harassment of players and interfere with the GTA Online experience for everybody. We are working to figure out how we can continue to support the creative community without negatively impacting our players."
